Got most things working. Did the 4 channel conversion on the stock Infinity amp and hooked up the subwoofer outputs to the back channel on the amp. Hooked the head unit back channels directly to the exciters on the back panel. Front door speakers used the stock hookup and wiring. I have not put bass blockers or applied sound absorption to the doors yet. Still have a bug with the backup light/camera wiring.

Sounds very good, but I have not taken it on the road yet. Seems to have no problems with signal level from the various outputs.

The radio did not need the software update for the Android Auto and Carplay

Two other parts that I had to order to convert the antennas (GPS, AM/FM)
